If the surroundings are designed to be sufficiently stimulating, even a simple computer screen is enough to generate an intense cinematic experience. After observing some 300 study subjects, researchers at the Institute of Psychology of Johannes Gutenberg University Mainz (JGU) concluded that the angle of viewing does not play a vital role in the cinematic experience, thus disproving various hypotheses. According to the results of their study, the presence of so-called contextual visual cues plays a greater role in actually drawing viewers into a movie. When the researchers gave a computer screen the attributes of a movie theater, the test subjects barely sensed a difference between it and a normal cinema with a large screen. Even a cell phone display performed relatively well in a cinematic environment.
